Abstract

PURPOSE:To eliminate an aldehyde evolved from a food using ethanol, etc., and protect the food against putrefaction and deterioration, by placing an adsorbent adsorbing ethanol, a readily oxidizable substance and aromatic aminosulfonic acid in a housing hermetically sealing a food so that ethanol vapor and oxygen may permeate. CONSTITUTION:An adsorbent adsorbing ethanol, e.g., silicon dioxide, readily oxidizable substance, e.g. oleic acid, and one or more of an aromatic aminosulfonic acid, e.g. sulfanilic acid, or an alkali metal salt or alkaline earth metal salt thereof are placed in a hermetically sealed housing containing a food in such a state that ethanol vapor and oxygen may permeate. The food, particularly using an alcohol is protected against putrefaction and deterioration. An oxidation accelerator, e.g. reduced iron, is preferably incorporated in the readily oxidizable substance.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to food preservatives and preservation methods, and in particular to improvements in food preservation using ethanol, and can be widely used in the food industry. It is something.

[Conventional technology]

Conventionally, C, A, (Controlled
Techniques for preserving foods under atomosphere conditions include vacuum, gas replacement, oxygen scavenger placement, and ethanol adsorbent placement. Recently, one of the inventors of the present invention has developed a food preservation method using an ethanol adsorbent, an easily oxidizable substance, and the oxidizable substance in combination with an oxidation promoter (Special Side No. 56-148271). .

Furthermore, the present inventor has discovered that the ethanol, the easily oxidizable substance, and the oxidation promoter for the easily oxidized substance are delayed under certain circumstances, i.e., during the production or use process, the ethanol adsorbent, the easily oxidizable substance, and the oxidation promoter are delayed. When exposed to the atmosphere for a long period of time, or when food manufacturers use this preservative, acetaldehyde is produced by exposure to the atmosphere for a long period of time. This was clarified in issue No.-127471.

[Problem that the invention seeks to solve]

The method described in JP-A-56-148271 had a high food preservation effect and was extremely effective in suppressing the growth of not only aerobic microorganisms but also anaerobic microorganisms.
In No. 27471, we also talked about the scavenging agents for acetaldehyde generated from ethanol under the specified conditions, but some of them have amino groups or sulfonic acid groups, but none of these are scavengers. It seems that the activity is high, and if they exist in one molecule, the effect can be exerted with a smaller amount of EI.The inventors searched for various compounds, and found that aromatic aminosulfonic acid contained in this compound. The present invention was completed by observing the effect of alkali metal salt injection on alkaline earth metal salts.

[Means to resolve all issues]

The ethanol adsorbent, the easily oxidizable substance, and the oxidation promoter for the easily oxidizable substance used in the present invention are all disclosed in JP-A No. 56-1
The following substances described in No. 48271 can be used. They are as follows.

In experiments of the present invention, searches were conducted using the following method. It was adsorbed with 0.6ri of ethanol and 0.47g of silicon dioxide, mixed with 1t of reduced iron and 0.29k of common salt, placed in a perforated polyethylene bag and sealed, wrapped in Japanese paper and left indoors for 2 hours. I learned that it is best to conduct experiments in a system in which a 1j capacity tank is placed in a spuck, deaerated, and then 300 m of air is introduced. At this time, in order to accelerate the oxidation of the easily oxidizable substance, it was placed in a tissue paper-1 gas pack that had absorbed 10-10% of water. All 3 of this gas bag
The gas pack was left to stand at 7° C., and the gas components in the gas pack, particularly the concentrations of ethanol, acetaldehyde, and oxygen, were measured using a gas chromatograph over time. As a result of various selections, it was discovered that aromatic aminosulfonic acids, their alkali metal salts, and their alkaline earth metal salts have remarkable scavenging ability. Sulfanilic acid.

Methanic acid, naphthionic acid, Tobias' acid or metal salts thereof are particularly preferred, but the invention is not limited to these compounds. In addition, these erasing agents are used in combination with an ethanol adsorbent, an easily oxidizable substance, and an oxidation promoter which is an easily oxidizable substance. Packed into the container made,
This is used by placing it in a closed storage container containing food. As food storage containers (manufactured, paper, wood 1 synthetic resin, glass, metal, ceramics, etc.) Materials such as boxes, bottles, cans, or cellophane, polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, metal foil, etc. Packaging bags made of can be used.

〔Example〕

Next, the method of the present invention will be specifically explained using Test Examples and Examples, but the present invention is not limited thereto.

Test Example Erasure of acetaldehyde generated in food preservatives 60 f of absolute ethanol and 40 t of silicon dioxide (Ad Solider 101, manufactured by Freund Sangyo Co., Ltd.) are mixed in a metal mortar, and reduced iron (manufactured by Wako Pure Chemical Industries, Ltd.) is mixed with 10 g of reduced iron (manufactured by Wako Pure Chemical Industries, Ltd.).

This was used as a total control. Prior to this, 17 gas banks? A 10-ml water-absorbed tissue paper was placed in each gas bank overnight. &2
After being left indoors for 2 hours, it was wrapped in the above Japanese paper and placed in a gas pack and sealed. Each of the samples listed in Table 1 was placed in A3 to Noff113, mixed by shaking the electrical equipment, heat sealed, left indoors for 2 hours, wrapped in the above-mentioned Japanese paper, and sealed in a Gaspak. For all gas banks after sealing, aspirator

(around 152) All three pieces were sealed. After degassing in the same manner as the test example, 300ml of air was introduced, and 37
It was left standing in a constant temperature chamber at ℃. When observed two weeks later, there was no change in the crepe at all.

As a control, an untreated crepe similar to the above was placed in a spuck, sealed, placed in a thermostat at 37°C and left to stand, and observed. There was mold all over.

The analysis values by gas chromatography after 2 weeks of the headspace of A1-YA13 were as shown in Table 2.

Is there an acetaldehyde smell when you open the Omote M-ya 2? I could smell it, but the only other smell was ethanol. Cut 2y of each of the crepes from &1 to ya13 into small pieces, put them in separate test tubes, and add 10 pieces each.
- Mix it with water and shake it vigorously to make Schick's reagent sound.
Only A2 had a positive aldehyde reaction, indicating that the crepe contained acetaldehyde. All other samples were negative.
